There is a bit more to it then that. Some people who disagree with how the
ORBS is run block their relay tests. The ORBS considers this grounds for
being listed as a potential relay since they can't test the site if their
test messages are blocked. The theory is, that they are worried about sites
blocking them, and not being able to list open relays for those sites.
I don't think this is really a good policy. The downside of the extra
coverage isn't worth the trouble. What they might lose, is the ability to
list some two-stage relays like demon. And blocking of two stage relays
is one of the problems people have with them. They do give the output
of two stage relays a few days to fix or block the input site, so it isn't
as big of a deal as it was.
